土壤中由于磷的固定造成作物可以吸收的有效磷较低,培育磷高效吸收的水稻新品种能够有助于解决缺磷所造成的农作物减产问题,为实现农业的可持续发展打下良好的基础。本文综述了水稻磷信号机制的最新研究进展,并总结了转基因改良水稻磷吸收效率的成功案例。这些改良策略对其他作物的转基因改良提供了重要的依据。
In the soil, the available phosphorus that the crops can absorb due to the fixation of phosphorus is low. Cultivating new varieties of rice with high absorption of phosphorus can help to reduce the crop yield reduction caused by phosphorus deficiency and lay a good foundation for the sustainable development of agriculture. This review summarizes the latest research progress of phosphorus signal mechanism in rice and summarizes the successful cases of transgene modification of phosphorus uptake efficiency in rice. These improved strategies provide an important basis for GMO improvement of other crops.
